Why You'll Love Trincomalee Trincomalee's deep natural harbour, one of the best in the world, has made it strategically important for centuries — today it's better known for calm, clear water diving and snorkelling, whale watching further offshore, and the clifftop Koneswaram Hindu temple overlooking the bay.
Calm seas and good visibility during the May-September season make Trincomalee one of Sri Lanka's most reliable diving bases — see the scuba diving in Trincomalee guide.
A Hindu temple perched on Swami Rock, a dramatic clifftop overlooking the harbour, with a history dating back over a thousand years.
Trincomalee's dry season runs roughly May to September, the opposite of the west and south coasts, making it a good alternate-season destination.
Combine scuba diving with a trip north to the quieter beaches of Nilaveli and Kuchchaveli. Background: Trincomalee on Wikipedia.
